3,6-Dichlorobenzene-1,2-dithiolate

Very recently, Hammarstrom, Ott, and coworkers found that the catalytic activity was significantly increased (up to 200 TON based on the iron complex) when a diiron complex having a 3,6-dichlorobenzene-1,2-dithiolate ligand (Fig. 10) instead of a benzylazadithiolate ligand was used as a WRC (see ref. [64] in [232]).

Direct formation of an organometallic complex 81 resulted when (r) -o-dichlorobenzene)(T) -cyclopentadienyl)iron(II) hexafluorophosphate was reacted with 4-methylbenzene-1,2-dithiol. The free 2-methylthianthrene could be released by heating the complex to 200-250°C (82JHC801). 4,5-...
